I got my Volcano yesterday, And it is awesome! Two things that you can't seem to tell from any of the product reviews out there: #1 it's size.. I was really nervous about this, but it was not nearly as big as I thought it would be.. It's footprint is actually a lot smaller than the zoo med waterfall (which I also purchased) It measures 10 inches high, and about 9-10 inches from corner to corner. It is not round like it appears in the pictures, it is actually a very nice sized corner piece. #2 and a big bonus is that it is hollow in the inside, so the two cave opening that you see in the pictures are actually entrances and it forms a nice sized cave for them to hide in.. the waterreservoir is built into the top 3 inches of the mountain, and everythng below that is all open space. I paid $39.99 for mine, which I thought was a great price since I had seen them for as much as $79. But when searching for size info I had run across
This site which sells them for $29.99.
I will post some pictures in the picture forum later.
